* backend: - refactor invite system, move to separate InviteOps object, used by archives and user - supporting three invite use cases: 1) superuser invites any user not registered, not added to any archive 2) archive admin invites any user not registered, add to one of their archives 3) archive admin invites existing registered user, add to one of their archives - support superadmin invite via /users/invite (fixes #37) - superadmin invite has no archive set and does not add user to archive - don't send verification email when accepting from invite, fixes #50 - use different email template / accept url for existing user invite, eg, `/invite/accept/` - fix default token value in chart
